RAILWAY-CAB BULSTEE.

`application mea April a,

The present invention relates to improvements in 'railwaycar bolsters, and has for an y object to provide a bolster in which the parts' are welded rather than riveted to secure advantages oi strength and serviceability notA possible with the old riveted bolster.

Another object ofthe invention is to provide a bolster ot maximum strength, having a minimum of material and in which the web is corrugated or iuted, thereby stiffening the web withoutincreasing theA thickness of the material; which type'ot web it has been impracticable tol use in fabricated holsters. lVith the foregoing and other objects in view, the invention will be more fully described hereinafter, .and will he more particularlypointed out in the claims appended hereto. t

ln the drawings, wherein like vsymbols refer to like or corresponding parts throughout the severallrviews, i

Figurev 1 is a top pian view of an improved bolster constructed according to the present invention; y

Figure 2 is a front elevation of the same; Figure 3 is a horizontal section taken'on the-line 3--3 in Figure 2; f

Figure 4 is a central vertical section taken along the line 4 4 in Figure 2;

Figure 5 is a similar section taken on the line '5--5 in Figure 2; and

Figure 6 is a transverse section taken on the line 6`6 also in Figure 2. y,

Referring more particularly to the drawings, 7 designates the upper tace plate to the. upper surface of which is attached the cenlter plate 8,and the side bearers 9. rlhe upper face plate 7 and the central lowermost part 10 of the lower face plate are joined cent-rally by a pipe section or bushing 11. The intermediate diagonal sections' 12 of the lower face plate and the end higher sections 13 thereo;E are joined to the lower edges of web plates 14.' These web plates are corrugated or luted according to any suitable construction, one instance of which is shown in the drawings at 15. Near the ends of the' bolster are attached the-guiding ribs 16 for the truck members (not shown). These guiding ribs are provided in spaced pairs, one pair being located to one side of each end oi the webs 14. These guiding ribs are preferably joined at their upper and lower edges to the upper and lower face plates.

The parts are all secured together by autogenous welding in place of rlveting. The

pipe or bushingll may bea cast or rolled member, welded, as showngin Figure 4, to the adyacent faces of theupper and lower face plates. This pipe or bushing is hollow, 6o l yet strong andj imparts rigidity tothe central portion of the holster, while conserving a great amount ot material and also admitting ot a considerable saving ot material of the webs, which, as indicated, are spaced from the pipe member 11, the'uted web providingfor stidening this member itself and the bolster generally Without increasing the thickness ot the web. The wingparts 13 of the holster rest on the springs and have such 7u I attachments as will give strength or serve other useful purpose, the-guiding ribslti being one'instance 'of a desirable attachment.

As shown in-Figure 5, the holster is of substantially til-section. As shown in Fig- 7e3 ure 6, the guide ribs 16 are preferably spaced from the webs 14. 'llhesev guiding ribs urther reinforcethe end construction of the olster.

As shown inlFigure t, the openings Hand 8f@ 18 through the upper and lowerftace vplates are inK line for the pin, and these openings are preferably smaller in diameter than the pipe section 11, and also than the diameter of ythe opening 19 in the central lplate 8. Se The diameter of this opening 19 is also pret,-

,erably smaller than the internal diameter of the pipe section 11. Thereby a.I mass ot f metal in the plate 8 exists to both inner and outer sides of the extended and the, upper face plate is reinforced over al large surface yat a point opposite Where the upper edge of the pipe section 11 engages same.

It will be obvious that many changes in the construction, combination and arrangement of parts 'could be made, which could be vused without departing from the spiritof my invention, and I do not mean lto'limitthe invention to suchsdetails, except as particularly pointed out the claims.

' Having thus A'described my invention, what claim and desire to secure by Letters Patent of the United States is :-v

. 1.y An electric welded railway car'bolster comprising upper and lowerlface plates,'a pipe section welded centrally to Ysaldupper and lower face plates, and corrugated webs extending on o posite sides of said pipe section and wel ed to ,the upper andlower faceplates. v

2. A elded railway car holster comprispipe section 11, 9u

ing upper and lower face plates, a pipe gsectionawelded centrally to the upper and lower face plates, webs welded to the upper and lower lface plates and extending in spaced relation and on opposite sides of said pipe section and forming with ythe face plates a bolster of substantially H-section.

3. A welded railway car bolster comprising upper and lower face plates, corrugated webs extending longitudinally thereof and welded to the adjacentfaces of the upper and lower faceplates alonga substantially longitudinal median line, said webs being spaced apartcentrally of the bloster, and a cylindrical bushingV extending between the face plates centrally of the bolster and weld-l ed to the adjacent faces of said face plates,

l, said bushing being spaced from the joining edges of the Webs. 2o

4. A welded railway car bolster comprising upper and lower face plates, luted` webs welded therebetween, a hollow pipe section weldedf centrally between fsaid face plates, and a center plate welded'tothe uppersurface of the upper face plate concentric-ally above said pipesection. l

5. A welded railway car bolster coinprisE in -upper and lower gface plates, longitudina central webs welded therebetween,a central hollow column weldedto the face plates,

a center plate weldedto the upper surface v of the upper face plate, and side .bearers alsowelded to the upper surface of said upper face plate. l

6. A weldedrailway car bolster comprising upper and lower face plates, webs welded therebetween, a `hollow post welded between said face plates, a center plate welded y to the upper face plate, and guiding ribs 'welded to the outer portions of said upper and lower face plates. v

7 lA welded railway car bolster comprising upper and lower face plates, the lower face plate having a central lowermost portion,'intermediate diagonal portions and up-` per outer portions, said upper and lower face plates having registering openings, fluted webs welded to the face plates, a hollow .pillar welded centrally to the face plates concentric with said openings and having an finternal diameter greater than the diameter ofsaid openings, and a center plate welded to the upper face plate and having` an open-l ing greater in diameter than said face plate openings, but of less diameter than the internal diameter of said hollow pillar.
